Ok, so I didn’t call it a smoothie for years to come…but it was the foundation for this yummy recipe! This smoothie has all the delicious flavors I remember from experimenting with my family, but it’s gained some nutritional values over the years. 

And a name that’s not stuck in the 80’s. But I digress.

If you’re looking for a smoothie that’s delicious enough to call a treat but healthy enough to have as a snack or light meal…I’ve got one you’ll love!

My Healthy Peanut Butter Banana Smoothie has the peanut butter-banana combo that reminds me of childhood, but healthy ingredients that pack a punch.

Between the almond milk, Greek yogurt, and rolled oats, you’ll have enough energy to keep you going all day. Ready to get started?

Why You’ll Love This Smoothie

• Five minutes, one blender. Everything goes in at once. No technique required.
• It actually fills you up. Greek yogurt and rolled oats give it staying power, so it’s a real breakfast, not a sugar spike.
• Naturally gluten-free with certified gluten-free oats, and easy to make dairy-free.
• Kids will drink it. It tastes like a milkshake, which makes it a quiet way to get something wholesome into a picky eater.
• Endlessly adjustable. Thicker, colder, greener, more chocolate. You can’t really get it wrong.

What’s In It

• Peanut butter. The flavor base. Powdered peanut butter (like PB2) blends smoothly and is a lighter option if you prefer it.
• Banana. Use a ripe one for sweetness, or a frozen one for a thicker, colder smoothie.
• Milk of choice. Almond, coconut, or dairy all work.
• Greek yogurt. Adds protein and that creamy, milkshake texture.
• Rolled oats. The secret to staying full. Use rolled, not instant, so the texture stays smooth. Bob’s Red Mill makes a reliable certified gluten-free oat, which matters in our house since my son and I are celiac.
• Chocolate chips and ice. A little chocolate for the treat factor, ice for the chill.

How to Make It

Add everything to the blender and blend until smooth. Breaking the banana into a few pieces helps it catch. Want it thicker or colder? Add more ice, or start with a frozen banana. Full measurements are in the recipe card below.

I love my Ninja blender for making smoothies, but the options below work well too.

Easy Variations

• Sneak in greens. A handful of spinach disappears completely behind the peanut butter and chocolate. You’ll never taste it.
• Make it dairy-free. Use a dairy-free milk and a dairy-free yogurt.
• Add a boost. A spoon of cocoa, a handful of berries, or a scoop of protein powder all fold in easily.
• Thicker or thinner. More oats and a frozen banana thicken it; a splash more milk loosens it.

Make It Ahead

Smoothies are best fresh, but you can prep freezer packs to make busy mornings even faster: portion the banana, oats, chocolate chips, and any add-ins into freezer bags, then dump a bag into the blender with your milk and yogurt when you’re ready. It’s a good job to hand a tween the night before.

Equipment

• Blender I love my Ninja, but any blender that will handle frozen items will work!

Ingredients

  

• 3 tbsp. of peanut butter add more to taste
• 1 small banana
• 3/4 cup almond milk, coconut milk, or dairy milk
• 1 cup plain or vanilla Greek yogurt
• 3 tbsp. of rolled oats Don’t use oatmeal – the texture will turn out oddly. Add more rolled oats for something thicker.
• Handful of chocolate chips
• Handful of ice

Instructions

 

• Put all of the ingredients into the blender. You may find it easier to break the banana into pieces. If you would like a thicker or colder smoothie, add a bit of extra ice.
• Blend all ingredients until they are smooth.
• Serve fresh and enjoy!

Notes

For an even healthier version, try powdered peanut butter (my favorite is PB2), which has less fat, calories, and oils compared to regular peanut butter. You simply mix it with water to get a good consistency. As a bonus, it is just made of crushed peanuts!

If you are looking for gluten free oats, Bob’s Red Mill is a fantastic source.

This makes one large smoothie or two small.
